South Korean Prime Minister Lee Wan-koo submitted his resignation Tuesday amid a growing corruption scandal.
Lee has been under pressure from the political opposition to step down as he faces bribery allegations in connection with large sums of government funds that went unaccounted for in state-directed overseas energy projects.
The scandal broke on April 9 when businessman Sung Wan-jong hanged himself on a hillside in Seoul, the South Korean capital. Under investigation for bribery, Sung left behind a note listing several high-ranking politicians next to figures said to indicate bribes. In the note, Sung claimed that in 2013 he gave the prime minister $27,600, hidden in boxes of a vitamin drink.
Sung was chairman of Keangnam Enterprises, a company that had been commissioned to invest government money in energy projects abroad. Lee touted the Keangnam projects, which are currently under investigation, as a financial boon for South Korea. The political opposition, however, accuses the ruling party of sinking billions of dollars into projects that have shown little returns.
Lee initially denied accepting any money from Sung and pledged to remain in his position.
